An investigation has been launched after two men were injured whilst setting up a stage at Miami's Ultra Music Festival.

One man was left with two fractured legs and another man was hurt after an LED screen fell from height onto the main stage last night (March 14).

The festival is taking place this year on the weekends of March 15-17 and March 22-24 with a host of massive names due to perform, including David Guetta and Deadmau5.

Engineers and emergency officials are now looking into why the screen fell onto the main stage and they will also investigate the structural competency of the festival's other stages.

It is unclear if the incident will affect the running of the festival this weekend, but the Ultra Music social networking websites indicate everything is set to go ahead as planned
